New FilterStage and more Flexible Totals

New FilterStage property on global_view determine if the list is
filtered or not. This is also true when showing category or account
lists.

Now Category can be selected from the category list and that shows all
the transactions from the selected category.

In order to fix the Totals labels issue, The
ReloadTransactionsActionsTotals function changed and now it can show The
totals on all cases:
ImportStage, FilterStage, Normal Transactions, Category or Account
lists.
RealodTransactionPageInterface Changed as well

Remember that when changing the lists there is not yet anything that
calls ReloadTransactionsActionsTotals therefore the totals will not get
updated on:
Deletion of items, Changes of amounts.
Ether on ImportStage, FilterStage or any other list.
